Lette/rs Patent No. 84,202, dated November 17, 1868.

IMPROVEMENT IN`HYDRANTS.

The Schedule referred to in these Letters Patent and making part of thesame.

` drants; and do hereby declare that the following is a full, clear, andexactv description of the same, reference being had to the accompanyingdrawings, making part of this specification, of which- Figure 1represents an elevation of my invention,

with part of enclosing `case removed;

Figure 2, a vertical section;

Figure .3, a horizontal section, on line x x,- and Figure 4, ahorizontal section, on line y y.

This invention relates to a novel and simple construction of a hydrant,and consists in arranging the discharge-pipe in such relation to themain supply-pipe as to cut off the supply of water from the main pipeuntil required for use, and after use, free the dischargepipe from Wastewater by an aperture in the base of the discharge-pipe, therebypreventing the effects of freezing by the action of the discharge-pipeitself,

rendering the hydrant automatic and self-protecting against frost.

In the said drawings, A denotes the water-main, connected vwith thedischarge-pipe B, by a pipe-coupling or plug-seat, C. This couplingembraces the plug D of the discharge-pipe, and contains a spiral spring,E, which is kept in place by acap, F, (screwed on to the coupling,) anda shoulder, G, on the plug. The coupling has also a shoulder, H, whichreceives a leather packing, I, on which the said plug rests.

The plug D tapers between kthe shoulder Gand the ends beyond thecoupling C, and

has a check, K, on its lower end. The said plug has also aninlet-opening, L, .for supply, and an outletopening, M for discharge ofthe waste water after the supply is obtained. (See fig. 2.) The saidplug D and discharge-pipe B, which constitute one piece, are pivoted inthe case at top, the nozzle d resting on the case, and are operated byalever or handle, N, attached to the case O, and to the saiddischarge-pipe B, asI

shown in 2 ofthe drawings.

The operation of my hydrant is as follows, viz:

IVhen it is desired to draw water from the hydrant, I merely lay hold'of the lever N, and leaning on the same, raise the discharge-pipe B Duntil the check K abuts againstthe plug-seat O, when the maininletopening L will. be brought in communication with the mainsupply-pipe A, and the required quantity drawn through the nozzle. Inthe mean time the waste-discharge opening M will be closed, and when thedesired supply is obtained, on lettingA go the lever N, the plug- D willbe returned to its original position by the action of the spiral springE, shutting off the supply from the Water-main, and opening thewaste-discharge M. 'And thus I produce a hydrant simple in construction,self-acting, and protecting against the effects of frost, and not liabletoget out of order.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

`The plu-g D, with openings of supply, L, and wastedischarge, M, incombination with the plug-seat C, spira-l spring E, and hand-lever N,operating together in manner substantially as and for the purposesdescribed an'd set forth. Y In testimony whereof, I have hereunto set mysignature, this day of July, A. D. 1868.
